USING LAPTOP WITHOUT BATTERY

EFFECT OF SUDDEN POWER OFF ON LAPTOP  WITHOUT BATTERY?

[Huffer]

Not good. Same as in a desktop and why do people use UPS'es in places prone to power surge? Laptop has a built in UPS called the battery. I recommend using it.

actually sir the life time of my battery is over so i can't use my battery as in built ups and i also won't to replace my battery because allmostly i use my laptop at home.i think it will be ok if i use my laptop without battery  and with continuously ac plug in on my home invetor which can be an external UPS for my laptop i i using my laptop withot battery.you mean to say sudden shutdown of my notebook is not good but it wil be ok if i use it without battery on any ups backup.

Sure the UPS will provide power backup same as to a desktop and same as a good laptop battery would.

just for knowladge sir i ask you,in what extent the sudden power cut or off can harm my laptop without battery.i mean to say is it harmful for my os or hard disk or system or any hardware disadvantage of it?please give me full detail about it sir.

Operating systems are complex and they must go through a “shutdown sequence” to make sure all running processes have correctly terminated before powering off. A sudden loss of electricity can interrupt important threads and leave your computer in an inoperable state.

System files are the largest concern. Consider what happens when a hard drive is writing data to the disk but suddenly shuts down in the middle of it. Suppose the file being written was a system file necessary for the booting process? Now that file is corrupted and you can’t boot up your computer without going through aninvolved recovery procedure.

Furthermore, frequent power outages can reduce a hard drive’s physical lifespan. The read-and-write head, which hovers over the spinning platters during operation, snaps back into its original position upon power loss. This sudden movement can cause tiny imperfections that accumulate over time, increasing the likelihood of a “head crash”: a malfunction that occurs when the head touches and scrapes the platter surfaces, effectively destroying the hard drive.

Solid-state drives can also suffer catastrophic damage from sudden power cuts. Issues can range anywhere from data corruption to total malfunction.

It should be noted that although power outages will not cause direct harm to computer hardware other than data drives, it’s possible for power outages to be accompanied by power surges, which can cause severe damage to hardware.
